FIELD OF THE INVENTION

The invention generally relates to the field of insect inhibitory proteins. A novel class of proteins are disclosed exhibiting insect inhibitory activity against agriculturally relevant pests of crop plants and seeds, particularly Lepidopteran species of insect plant pests. Provided are plants, plant parts, seed, cells including plant as well as bacterial cells, and vectors, each respectively containing a recombinant polynucleotide construct comprising in operable linkage a heterologous promoter and a polynucleotide segment encoding one or more of the disclosed toxin proteins.

BACKGROUND OF THE INVENTION

Improving crop yield from agriculturally significant plants including, among others, corn, soybean, sugarcane, rice, wheat, canola, vegetables, and cotton, has become increasingly important. In addition to the growing need for agricultural products to feed, clothe and provide energy for a growing human population, climate-related effects and pressure from the growing population to use land other than for agricultural practices are predicted to reduce the amount of arable land available for farming. These factors have led to grim forecasts of food security, particularly in the absence of major improvements in plant biotechnology and agronomic practices. In light of these pressures, environmentally sustainable improvements in technology, agricultural techniques, and pest management are vital tools to expand crop production on the limited amount of arable land available for farming.

Insects, particularly insects within the order Lepidoptera, are considered a major cause of damage to field crops, thereby decreasing crop yields over infested areas. Lepidopteran pest species which negatively impact agriculture include, but are not limited to, Black armyworm (Spodoptera cosmioides), Black cutworm (Agrotis ipsilon), Corn earworm (Helicoverpa zea), Cotton leaf worm (Alabama argillacea), Diamondback moth (Plutella xylostella), European corn borer (Ostrinia nubilalis), Fall armyworm (Spodoptera frugiperda), Cry1Fa1 resistant Fall armyworm (Spodoptera frugiperda), Old World bollworm (OWB, Helicoverpa armigera), Southern armyworm (Spodoptera eridania), Soybean looper (Chrysodeixis includens), Spotted bollworm (Earias vittella), Southwestern corn borer (Diatraea grandiosella), Sugarcane borer (Diatraea saccharalis), Sunflower looper (Rachiplusia nu), Tobacco budworm (Heliothis virescens), Tobacco cutworm (Spodoptera litura, also known as cluster caterpillar), Western bean cutworm (Striacosta albicosta), and Velvet bean caterpillar (Anticarsia gemmatalis).

Historically, the intensive application of synthetic chemical insecticides was relied upon as the pest control agent in agriculture. Concerns for the environment and human health, in addition to emerging resistance issues, stimulated the research and development of biological pesticides. This research effort led to the progressive discovery and use of various entomopathogenic microbial species, including bacteria.

The biological control paradigm shifted when the potential of entomopathogenic bacteria, especially bacteria belonging to the genus Bacillus, was discovered and developed as a biological pest control agent. Strains of the bacterium Bacillus thuringiensis (Bt) have been used as a source for pesticidal proteins since it was discovered that Bt strains show a high toxicity against specific insects. Bt strains are known to produce delta-endotoxins that are localized within parasporal crystalline inclusion bodies at the onset of sporulation and during the stationary growth phase (e.g., Cry proteins), and are also known to produce secreted insecticidal protein. Upon ingestion by a susceptible insect, delta-endotoxins as well as secreted toxins exert their effects at the surface of the midgut epithelium, disrupting the cell membrane, leading to cell disruption and death. Genes encoding insecticidal proteins have also been identified in bacterial species other than Bt, including other Bacillus and a diversity of additional bacterial species, such as Brevibacillus laterosporus, Lysinibacillus sphaericus (“Ls” formerly known as Bacillus sphaericus), Paenibacillus popilliae and Paenibacillus lentimorbus. In addition, insecticidal toxins have also been identified from a variety of non-bacterial sources including ferns, arachnid venoms, and delivery in a diet of a pest of dsRNA targeting an essential gene for suppression has been identified as an effective pest management strategy.

Crystalline and secreted soluble insecticidal toxins are highly specific for their hosts and have gained worldwide acceptance as alternatives to chemical insecticides. For example, insecticidal toxin proteins have been employed in various agricultural applications to protect agriculturally important plants from insect infestations, decrease the need for chemical pesticide applications, and increase yields. Insecticidal toxin proteins are used to control agriculturally-relevant pests of crop plants by mechanical methods, such as spraying to disperse microbial formulations containing various bacteria strains onto plant surfaces, and by using genetic transformation techniques to produce transgenic plants and seeds expressing insecticidal toxin protein(s).

The use of transgenic plants expressing insecticidal toxin proteins has been globally adapted. For example, in 2016, 23.1 million hectares were planted with transgenic crops expressing Bt toxins and 75.4 million hectares were planted with transgenic crops expressing Bt toxins stacked with herbicide tolerance traits (ISAAA. 2016. Global Status of Commercialized Biotech/GM Crops: 2016. ISAAA Brief No. 52. ISAAA: Ithaca, N.Y.). The global use of transgenic insect-protected crops and the limited number of insecticidal toxin proteins used in these crops has created a selection pressure for existing insect alleles that impart resistance to the currently-utilized insecticidal proteins.

The development of resistance in target pests to insecticidal toxin proteins creates the continuing need for discovery and development of new forms of insecticidal toxin proteins that are useful for managing the increase in insect resistance to transgenic crops expressing insecticidal toxin proteins. New protein toxins with improved efficacy and which exhibit control over a broader spectrum of susceptible insect species will reduce the number of surviving insects which can develop resistance alleles. In addition, the use in one plant of two or more transgenic insecticidal toxin proteins toxic to the same insect pest and displaying different modes of action or alternatively two or more different modes of toxic action (for example, a transgene encoding a dsRNA targeting an essential gene for suppression coupled with a transgene that encodes a peptide or protein toxin, both toxic to the same insect species) reduces the probability of resistance in any single target insect species. Additionally, use of self-limiting technologies such as those provided by Oxitec Ltd, when used together with the proteins of the present invention, should improve durability of the traits imparted to transgenic crops expressing proteins of the present invention (Zhou et al. 2018, Evol Appl 11(5):727-738; Alphey et al., 2009, Journal of Economic Enontogy, 102: 717-732).

Thus, the inventors disclose herein a novel protein from Bacillus thuringiensis, along with engineered variant proteins, and exemplary recombinant proteins, that each exhibit insecticidal activity against target Lepidopteran species, particularly against Black armyworm (Spodoptera cosmioides), Black cutworm (Agrotis ipsilon), Corn earworm (Helicoverpa zea), European corn borer (Ostrinia nubilalis), South American pod worm (Helicoverpa gelotopoeon), Southern armyworm (Spodoptera eridania), Soybean looper (Chrysodeixis includens), Southwestern corn borer (Diatraea grandiosella), Tobacco budworm (Heliothis virescens), and Velvet bean caterpillar (Anticarsia gemmatalis).

DETAILED DESCRIPTION OF THE INVENTION

One problem in the art of agricultural pest control can be characterized as a need for new toxin proteins that are efficacious against target pests, exhibit broad spectrum toxicity against target pest species, are capable of being expressed in plants without causing undesirable agronomic issues, and provide an alternative mode of action compared to current toxins that are used commercially on or in plants.

Novel pesticidal proteins exemplified by TIC4064 and engineered amino acid sequence variants are disclosed herein and address each of these problems in the art, particularly against a broad spectrum of Lepidopteran insect pests of crop plants, and for instance against Black armyworm (Spodoptera cosmioides), Black cutworm (Agrotis ipsilon), Corn earworm (Helicoverpa zea), European corn borer (Ostrinia nubilalis), South American podworm (Helicoverpa gelotopoeon), Southern armyworm (Spodoptera eridania), Soybean looper (Chrysodeixis includens), Southwestern corn borer (Diatraea grandiosella), Sunflower looper (Rachiplusia nu), Tobacco budworm (Heliothis virescens), and Velvet bean caterpillar (Anticarsia gemmatalis).

Reference in this application to TIC4064, “TIC4064 protein”, “TIC4064 protein toxin”, “TIC4064 pesticidal protein”, “TIC4064-related toxins”, “TIC4064-related toxins”, “TIC4064 class”, “TIC4064 protein toxin class”, “TIC4064 toxin protein class”, and the like, which are substantially interchangeable terms, refer to any novel pesticidal protein or insect inhibitory protein, that comprises, that consists of, that is substantially homologous to, that is similar to, or that is derived from any pesticidal protein or insect inhibitory protein sequence of TIC4064 (SEQ ID NO:2), and the amino acid sequence variant TIC4064 toxin proteins, TIC40641 (SEQ ID NO:4), TIC4064_2 (SEQ ID NO:6), TIC4064_3 (SEQ ID NO:8), TIC4064_4 (SEQ ID NO:10), TIC4064_5 (SEQ ID NO:12), TIC4064_6 (SEQ ID NO:14), TIC4064_12_1 (SEQ ID NO:16), TIC4064_12_2 (SEQ ID NO:18), TIC4064_13 (SEQ ID NO:20), TIC4064_14 (SEQ ID NO:22), TIC4064_15 (SEQ ID NO:24), TIC4064_16 (SEQ ID NO:26), TIC4064_17 (SEQ ID NO:28), TIC4064_18 (SEQ ID NO:30), TIC4064_19 (SEQ ID NO:32), TIC4064_20 (SEQ ID NO:34), TIC4064_21 (SEQ ID NO:36), TIC4064_22 (SEQ ID NO:38), TIC4064_23 (SEQ ID NO:40), TIC4064_24 (SEQ ID NO:42), TIC4064_25 (SEQ ID NO:44), TIC4064_26 (SEQ ID NO:46). TIC4064_27 (SEQ ID NO:48), TIC4064_11 (SEQ ID NO:50), and TIC4064_11 (SEQ ID NO:52) and pesticidal or insect inhibitory segments, or combinations thereof, that confer activity against Lepidopteran pests, including any protein exhibiting pesticidal or insect inhibitory activity if alignment of such protein with TIC4064 results in an amino acid sequence of identity of any fraction percentage from about 98% to about 100% percent. The TIC4064 proteins include both the plastid-targeted and non-plastid targeted forms of the proteins.

The term “segment” or “fragment” is used in this application to describe consecutive amino acid or nucleic acid sequences that are shorter than the complete amino acid or nucleic acid sequence describing TIC4064 or a TIC4064 variant protein or the respective nucleotide sequences encoding such amino acid sequences. A segment or fragment exhibiting insect inhibitory activity is also disclosed in this application if alignment of such segment or fragment, with the corresponding section of the TIC4064 protein set forth in SEQ ID NO:2, the TIC4064_1 protein set forth in SEQ ID NO:4, the TIC4064_2 protein set forth in SEQ ID NO:6, the TIC4064_3 protein set forth in SEQ ID NO:8, the TIC4064_4 protein set forth in SEQ ID NO:10, the TIC4064_5 protein set forth in SEQ ID NO:12, the TIC4064_6 protein set forth in SEQ ID NO:14, the TIC4064_12_1 protein set forth in SEQ ID NO:16, the TIC4064_12_2 protein set forth in SEQ ID NO:18, the TIC4064_13 protein set forth in SEQ ID NO:20, the TIC4064_14 protein set forth in SEQ ID NO:22, the TIC4064_15 protein set forth in SEQ ID NO:24, the TIC4064_16 protein set forth in SEQ ID NO:26, the TIC4064_17 protein set forth in SEQ ID NO:28, the TIC4064_18 protein set forth in SEQ ID NO:30, the TIC4064_19 protein set forth in SEQ ID NO:32, the TIC4064_20 protein set forth in SEQ ID NO:34, the TIC4064_21 protein set forth in SEQ ID NO:36, the TIC4064_22 protein set forth in SEQ ID NO:38, the TIC4064_23 protein set forth in SEQ ID NO:40, the TIC4064_24 protein set forth in SEQ ID NO:42, the TIC4064_25 protein set forth in SEQ ID NO:44, the TIC4064_26 protein set forth in SEQ ID NO:46, the TIC4064_27 protein set forth in SEQ ID NO:48, the TIC4064_10 protein set forth in SEQ ID NO:50, or the TIC4064_11 protein set forth in SEQ ID NO:52, results in amino acid sequence identity of any fraction percentage from about 85 to about 100 percent between the segment or fragment and the corresponding segment of amino acids within the TIC4064, or TIC4064 amino acid sequence variant proteins. A fragment as described herein may comprise at least 50, at least 100, at least 250, at least 400, at least 500, at least 600, at least 800, or at least 1000 contiguous amino acid residues of TIC4064, or of a TIC4064 amino acid sequence variant protein. A fragment as described herein may display the pesticidal activity of any of TIC4064, or of a TIC4064 amino acid sequence variant protein.

Reference in this application to the terms “active” or “activity”, “pesticidal activity” or “pesticidal” or “insecticidal activity”, “insect inhibitory”, “pesticidally effective” or “insecticidal” refer to efficacy of a toxic agent, such as a protein toxin, in inhibiting (inhibiting growth, feeding, fecundity, or viability), suppressing (suppressing growth, feeding, fecundity, or viability), controlling (controlling the pest infestation, controlling the pest feeding activities on a particular crop) containing an effective amount of the TIC4064 toxin protein class protein or killing (causing the morbidity, mortality, or reduced fecundity of) a pest. These terms are intended to include the result of providing a pesticidally effective amount of a toxic protein to a pest where the exposure of the pest to the toxic protein results in morbidity, mortality, reduced fecundity, or stunting. These terms also include repulsion of the pest from the plant, a tissue of the plant, a plant part, seed, plant cells, or from the particular geographic location where the plant may be growing, as a result of providing a pesticidally effective amount of the toxic protein in or on the plant. In general, pesticidal activity refers to the ability of a toxic protein to be effective in inhibiting the growth, development, viability, feeding behavior, mating behavior, fecundity, or any measurable decrease in the adverse effects caused by an insect feeding. The toxic protein can be produced by the plant or can be applied to the plant or to the environment within the location where the plant is located. The terms “bioactivity”, “effective”, “efficacious” or variations thereof are also terms interchangeably utilized in this application to describe the effects of proteins of the present invention on target insect pests.

A pesticidally effective amount of a toxic agent, when provided in the diet of a target pest, exhibits pesticidal activity when the toxic agent contacts the pest. A toxic agent can be a pesticidal protein or one or more chemical agents known in the art. Pesticidal or insecticidal chemical agents can be used alone or in combinations with each other. Chemical agents include but are not limited to dsRNA molecules targeting specific genes for suppression in a target pest, organochlorides, organophosphates, carbamates, pyrethroids, neonicotinoids, and ryanoids. Pesticidal or insecticidal protein agents include the protein toxins set forth in this application, as well as other proteinaceous toxic agents including those that target Lepidopterans, as well as protein toxins that are used to control other plant pests such as Cry, Vip, and Cyt proteins available in the art for use in controlling Coleopteran, Hemipteran and Homopteran species.

It is intended that reference to a pest, particularly a pest of a crop plant, means insect pests of crop plants, particularly those Lepidoptera insect pests that are controlled by the TIC4064 protein toxin class. However, reference to a pest can also include Coleopteran, Hemipteran and Homopteran insect pests of plants, as well as nematodes and fungi when toxic agents targeting these pests are co-localized or present together with the TIC4064 protein or the amino acid sequence variant TIC4064 proteins or a protein that is 85 to about 100 percent identical to TIC4064 protein or the amino acid sequence variant TIC4064 proteins. The phrases “present together” and “co-located” are intended to include any instance of which a target insect pest has been contacted by the TIC4064 protein toxin class as well as any other toxic agent also present in a pesticidally effective amount relative to the target insect pest. “Contacted” is intended to refer to being present in the diet of the target pest, and the diet is, at least in part, consumed or ingested by the target pest in an amount sufficient to deliver to the target pest a pesticidally effective amount of the toxic agent and TIC4064 class toxin protein.

The TIC4064 protein or amino acid sequence variant TIC4064 proteins are related by a common function and exhibit insecticidal activity towards insect pests from the Lepidoptera insect species, including adults, pupae, larvae, and neonates.

The insects of the order Lepidoptera include, but are not limited to, armyworms, cutworms, loopers, and heliothines in the family Noctuidae, e.g., Fall armyworm (Spodoptera frugiperda), Beet armyworm (Spodoptera exigua), Black armyworm (Spodoptera cosmioides), Southern armyworm (Spodoptera eridania), bertha armyworm (Mamestra configurata), black cutworm (Agrotis ipsilon), cabbage looper (Trichoplusia ni), soybean looper (Pseudoplusia includens), Sugarcane borer (Diatraea saccharalis), Sunflower looper (Rachiplusia nu), velvetbean caterpillar (Anticarsia gemmatalis), green cloverworm (Hypena scabra), tobacco budworm (Heliothis virescens), granulate cutworm (Agrotis subterranea), armyworm (Pseudaletia unipuncta), Sunflower looper (Rachiplusia nu), South American podworm (Helicoverpa gelotopoeon), western cutworm (Agrotis orthogonia); borers, casebearers, webworms, coneworms, cabbageworms and skeletonizers from the Family Pyralidae, e.g., European corn borer (Ostrinia nubilalis), navel orange worm (Amyelois transitella), corn root webworm (Crambus caliginosellus), sod webworm (Herpetogramma licarsisalis), sunflower moth (Homoeosoma electellum), lesser cornstalk borer (Elasmopalpus lignosellus); leafrollers, budworms, seed worms, and fruit worms in the Family Tortricidae, e.g., codling moth (Cydia pomonella), grape berry moth (Endopiza viteana), oriental fruit moth (Grapholita molesta), sunflower bud moth (Suleima helianthana); and many other economically important Lepidoptera, e.g., diamondback moth (Plutella xylostella), pink bollworm (Pectinophora gossypiella), and gypsy moth (Lymantria dispar). Other insect pests of order Lepidoptera include, e.g., cotton leaf worm (Alabama argillacea), fruit tree leaf roller (Archips argyrospila), European leafroller (Archips rosana) and other Archips species, (Chilo suppressalis, Asiatic rice borer, or rice stem borer), rice leaf roller (Cnaphalocrocis medinalis), corn root webworm (Crambus caliginosellus), bluegrass webworm (Crambus teterrellus), southwestern corn borer (Diatraea grandiosella), surgarcane borer (Diatraea saccharalis), spiny bollworm (Earias insulana), spotted bollworm (Earias vittella), American bollworm (Helicoverpa armigera), corn earworm (Helicoverpa zea, also known as soybean pod worm and cotton bollworm), tobacco budworm (Heliothis virescens), sod webworm (Herpetogramma licarsisalis), Western bean cutworm (Striacosta albicosta), European grape vine moth (Lobesia botrana), citrus leaf miner (Phyllocnistis citrella), large white butterfly (Pieris brassicae), small white butterfly (Pieris rapae, also known as imported cabbageworm), beet armyworm (Spodoptera exigua), tobacco cutworm (Spodoptera litura, also known as cluster caterpillar), and tomato leaf miner (Tuta absoluta).

Reference in this application to an “isolated DNA molecule”, or an equivalent term or phrase, is intended to mean that the DNA molecule is one that is present alone or in combination with other compositions, but not within its natural environment. For example, nucleic acid elements such as a coding sequence, intron sequence, untranslated leader sequence, promoter sequence, transcriptional termination sequence, and the like, that are naturally found within the DNA of the genome of an organism are not considered to be “isolated” so long as the element is within the genome of the organism and at the location within the genome in which it is naturally found. However, each of these elements, and subparts of these elements, would be “isolated” within the scope of this disclosure so long as the element is not within the genome of the organism nor at the location within the genome in which it is naturally found. Similarly, a nucleotide sequence encoding an insecticidal protein or any naturally occurring insecticidal variant of that protein would be an isolated nucleotide sequence so long as the coding sequence was not within the DNA of the organism from which the sequence encoding the protein is naturally found. A synthetic or artificial nucleotide sequence encoding the amino acid sequence of the naturally occurring insecticidal protein or a variant sequence thereof would be considered to be isolated for the purposes of this disclosure. For the purposes of this disclosure, any transgenic nucleotide sequence, i.e., the nucleotide sequence of the DNA inserted into the genome of the cells of a plant or bacterium, or present in an extrachromosomal vector, would be considered to be an isolated nucleotide sequence whether it is present within the plasmid or similar structure used to transform the cells, within the genome of the plant or bacterium, or present in detectable amounts in tissues, progeny, biological samples or commodity products derived from the plant or bacterium. A protein would be isolated if it were produced in a space in which it was not normally found to be produced in nature, i.e. in a transgenic or recombinant cell, in a transgenic or recombinant bacterium. Proteins and polynucleotide sequences/coding sequences can be isolated from the organism in which these are produced, i.e. any number of means known in the art, such as filtration, precipitation, capture (using various molecules which exhibit affinity specifically to the protein or nucleic acid structure), and the like, further “isolating” the molecules from constituents that create an impurity and the like. A recombinant cell, whether plant or bacterium, by its very nature is not naturally occurring, is isolated, and so is not a product of nature, and so is patentable in every territory in the world on this basis. Similarly, transgenic plants and plant products are not products of nature, not naturally occurring, and so are also isolated from other natural products and phenomenon and so are thus patentable subject matter in every territory.

Reference in this application to the term “self-limiting gene” refers to a gene that limits survival of the host, resulting in a reduction in the host population. Such technology is offered by Oxitech Ltd. and other unrelated entities. Transgenic male insects carrying one or more transgenic self-limiting genes are released and reproduce with wild females. As a result, the progeny inherit a copy of the self-limiting gene. The self-limiting gene disrupts the proper functioning of the insects' cells by over-producing a protein in them, interfering with the cells' ability to produce other essential proteins needed for development. By disrupting the insect's normal development, the gene prevents it from surviving to adulthood. For example, the self-limiting Diamondback Moth (Plutella xylostella) strain OX4319L was developed by Oxitech Ltd and carries a male-selecting gene that utilizes sequences from the sex determination gene doublesex (dsx). The gene expresses sex-alternate splicing, to engineer female-specific expression of the self-limiting gene which prevents survival of female offspring beyond the larval stage and allows for production of male only cohorts of self-limiting moths. After being released, males mate with pest females, leading to a reduction in the number of female offspring in the next generation, thereby locally suppressing P. xylostella populations. To facilitate the rearing of large numbers of males for release within diamondback moth production facilities, the expression of female-specific dsx within the OX4319L strain is repressed by the addition of tetracycline, or suitable analogs, into the larval feed. OX4319L also expresses the fluorescent protein, DsRed, to permit the effective monitoring of the presence of this strain in the field (Jin et al., 2013. Engineered female-specific lethality for control of pest Lepidoptera. ACS Synthetic Biology, 2: 160-166). This self-limiting technology, when applied in the field with plants containing the toxin genes of the present invention, can delay or prevent the onset of resistance of pest species targeted for control by the toxin genes and proteins of the present invention, thus giving a greater durability of any plant product containing the toxin genes and proteins of the present invention. Each of the insect species as set forth in this specification at paragraph [0086] are intended to be within the scope of those that are susceptible to, and thus amenable to reliance upon, the self-limiting technology described herein.

As described further in this application, an open reading frame (ORF) encoding TIC4064 (SEQ ID NO:1) was discovered in DNA obtained from Bacillus thuringiensis strain EG9820. The coding sequence was cloned and expressed in microbial host cells to produce recombinant proteins used in bioassays. Bioassay using microbial host cell-derived proteins of TIC4064 demonstrated activity against the Lepidopteran species Black cutworm (BCW, Agrotis ipsilon), Corn earworm (CEW, Helicoverpa zea), European corn borer (ECB, Ostrinia nubilalis), Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Southwestern corn borer (SWC, Diatraea grandiosella), Tobacco budworm (TBW, Heliothis virescens), Sunflower looper (SFL, Rachiplusia nu), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis). Engineered bacterial expressed amino acid sequence variants were produced using the TIC4064 amino acid sequence resulting in the amino acid sequence variants TIC4064_20 (SEQ ID NO:34), TIC4064_21 (SEQ ID NO:36), TIC4064_22 (SEQ ID NO:38), TIC4064_23 (SEQ ID NO:40), TIC4064_24 (SEQ ID NO:42), TIC4064_25 (SEQ ID NO:44), TIC4064_26 (SEQ ID NO:46) TIC4064_27 (SEQ ID NO:48), TIC4064_10 (SEQ ID NO:50), and TIC4064_11 (SEQ ID NO:52) encoded by SEQ ID NO:33, SEQ ID NO:35, SEQ ID NO:37, SEQ ID NO:39, SEQ ID NO:41, SEQ ID NO:43, SEQ ID NO:45, SEQ ID NO:47, SEQ ID NO:49, and SEQ ID NO:51, respectively.

Synthetic (artificial) coding sequences designed for use in a plant cell were produced to express TIC4064 and amino acid sequence variants of TIC4064 wherein an alanine codon has been inserted as the second codon in the open reading frame, resulting in TIC4064_1 (SEQ ID NO:4), and the amino acid sequence variants TIC4064_2 (SEQ ID NO:6), TIC4064_3 (SEQ ID NO:8), TIC4064_4 (SEQ ID NO:10), TIC4064_5 (SEQ ID NO:12), TIC4064_6 (SEQ ID NO:14), TIC4064_12_1 (SEQ ID NO:16), TIC4064_12_2 (SEQ ID NO:18), TIC4064_13 (SEQ ID NO:20), TIC4064_14 (SEQ ID NO:22), TIC4064_15 (SEQ ID NO:24), TIC4064_16 (SEQ ID NO:26), TIC4064_17 (SEQ ID NO:28), TIC4064_18 (SEQ ID NO:30), and TIC4064_19 (SEQ ID NO:32), encoded by the coding sequences SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:29, and SEQ ID NO:31, encoding TIC4064_1 (SEQ ID NO:4), respectively.

TIC4064_3 and TIC4064_4 also demonstrated efficacy against SBL, VBC, and SFL (Sunflower looper, Rachiplusia nu), and suppression of SAPW (South American podworm, Helicoverpa gelotopoeon) when tested in screenhouse trails.

For expression in plant cells, the TIC4064_1 (SEQ ID NO:4), TIC4064_2 (SEQ ID NO:6), TIC4064_3 (SEQ ID NO:8), TIC4064_4 (SEQ ID NO:10), TIC4064_5 (SEQ ID NO:12), TIC4064_6 (SEQ ID NO:14), TIC4064_12_1 (SEQ ID NO:16), TIC4064_12_2 (SEQ ID NO:18), TIC4064_13 (SEQ ID NO:20), TIC4064_14 (SEQ ID NO:22), TIC4064_15 (SEQ ID NO:24), TIC4064_16 (SEQ ID NO:26), TIC4064_17 (SEQ ID NO:28), TIC4064_18 (SEQ ID NO:30), and TIC4064_19 (SEQ ID NO:32) proteins can be expressed to accumulate in the cytosol or in various organelles of the plant cell. For example, targeting a protein to the chloroplast may result in increased levels of expressed protein in a transgenic plant while preventing off-phenotypes from occurring. Targeting may also result in an increase in pest resistance efficacy in the transgenic event. Targeting peptides or transit peptides are known in the art and when attached to a protein of interest, direct the transport of the protein of interest to a specific region in the cell, including for example the nucleus, mitochondria, endoplasmic reticulum (ER), chloroplast, apoplast, peroxisome and plasma membrane. Some targeting peptides are cleaved from the protein of interest by signal peptidases after the protein is transported through a particular membrane. For targeting to the chloroplast, proteins contain transit peptides which are around 40-50 amino acids in length. For descriptions of the use of chloroplast transit peptides, see U.S. Pat. Nos. 5,188,642 and 5,728,925. Many naturally occurring chloroplast-localized proteins are expressed from nuclear genes as precursors and are targeted to the chloroplast by a chloroplast transit peptide (CTP). Examples of such isolated CTPs include, but are not limited to, those associated with the small subunit (SSU) of ribulose-1,5,-bisphosphate carboxylase, ferredoxin, ferredoxin oxidoreductase, the light-harvesting complex protein I and protein II, thioredoxin F, enolpyruvyl shikimate phosphate synthase (EPSPS), and transit peptides described in U.S. Pat. No. 7,193,133. It has been demonstrated in vivo and in vitro that non-chloroplast proteins may be targeted to the chloroplast by use of protein fusions with a heterologous CTP and that the CTP is sufficient to target a protein to the chloroplast. Incorporation of a suitable chloroplast transit peptide such as the Arabidopsis thaliana EPSPS CTP (CTP2) (see, Klee et al., Mol. Gen. Genet. 210:437-442, 1987) or the Petunia hybrida EPSPS CTP (CTP4) (see, della-Cioppa et al., Proc. Natl. Acad. Sci. USA 83:6873-6877, 1986) has been shown to target heterologous EPSPS protein sequences to chloroplasts in transgenic plants (see, U.S. Pat. Nos. 5,627,061; 5,633,435; and 5,312,910; and EP 0218571; EP 189707; EP 508909; and EP 924299). For targeting the TIC4064 or the amino acid sequence variant TIC4064 toxin protein to the chloroplast, a sequence encoding a chloroplast transit peptide is placed 5′ in operable linkage and in frame to a synthetic (artificial) coding sequence encoding the TIC4064 or the amino acid sequence variant TIC4064 toxin protein that has been designed for expression in plant cells.

It is contemplated that additional toxin protein sequences related to TIC4064 can be created using the amino acid sequence of TIC4064 to create novel proteins with novel properties. The TIC4064 toxin proteins can be aligned to combine differences at the amino acid sequence level into novel amino acid sequence variants and making appropriate changes to the recombinant nucleic acid sequence encoding such variants.

It is contemplated that improved variants of the TIC4064 protein toxin class can be engineered in planta by using various gene editing methods known in the art. Such technologies used for genome editing include, but are not limited to, ZFN (zinc-finger nuclease), meganucleases, TALEN (Transcription activator-like effector nucleases), and CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/Cas (CRISPR-associated) systems. These genome editing methods can be used to alter the toxin protein coding sequence transformed within a plant cell to a different toxin coding sequence. Specifically, through these methods, one or more codons within the toxin coding sequence is altered to engineer a new protein amino acid sequence. Alternatively, a fragment within the coding sequence is replaced or deleted, or additional DNA fragments are inserted into the coding sequence, to engineer a new toxin coding sequence. The new coding sequence can encode a toxin protein with new properties such as increased activity or spectrum against insect pests, as well as provide activity against an insect pest species wherein resistance has developed against the original insect toxin protein. The plant cell comprising the gene edited toxin coding sequence can be used by methods known in the art to generate whole plants expressing the new toxin protein.

It is also contemplated that fragments of TIC4064 or protein variants thereof can be truncated forms wherein one or more amino acids are deleted from the N-terminal end, C-terminal end, the middle of the protein, or combinations thereof wherein the fragments and variants retain insect inhibitory activity. These fragments can be naturally occurring or synthetic variants of TIC4064 or derived protein variants but should retain the insect inhibitory activity of at least TIC4064.

Proteins that resemble the TIC4064 proteins can be identified and compared to each other using various computer-based algorithms known in the art (see Tables 2 through 6). Amino acid sequence identities reported in this application are a result of a Clustal W alignment using these default parameters: Weight matrix: blosum, Gap opening penalty: 10.0, Gap extension penalty: 0.05, Hydrophilic gaps: On, Hydrophilic residues: GPSNDQERK, Residue-specific gap penalties: On (Thompson, et al (1994) Nucleic Acids Research, 22:4673-4680). Percent amino acid identity is further calculated by the formula: 100% multiplied by (amino acid identities/length of subject protein). Other alignment algorithms are also available in the art and provide results similar to those obtained using a Clustal W alignment and are contemplated herein.

It is intended that a protein exhibiting insect inhibitory activity against a Lepidopteran insect species is related to TIC4064 if the protein is used in a query, e.g., in a Clustal W alignment, and the proteins of the present invention as set forth as SEQ ID NO:2 are identified as hits in such alignment in which the query protein exhibits at least 98% to about 100% amino acid sequence identity along the length of the amino acids in the query protein that is about 98%, 99%, 100%, or any fraction percentage in this range.

Exemplary bacterial expressed TIC4064 protein and amino acid sequence variants were aligned with each other using a Clustal W algorithm. A pair-wise matrix of percent amino acid sequence identities for each of the full-length proteins was created, as reported in Tables 2 and 3.

As described further in the Examples of this application, synthetic nucleic acid molecule sequences encoding TIC4064_1, TIC4064_2, TIC4064_3, TIC4064_4, TIC4064_5, TIC4064_6, TIC4064_12_1, TIC4064_12_2, TIC4064_13, TIC4064_14, TIC4064_15, TIC4064_16, TIC4064_17, TIC4064_18, and TIC4064_19 were designed for use in plants, encoded by SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO: 11, SEQ ID NO: 13, SEQ ID NO: 15, SEQ ID NO: 17, SEQ ID NO: 19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:29, and SEQ ID NO:31, respectively. Each of the variant proteins has an alanine amino acid added at position two (2) of the amino acid sequence, immediately following the initiating methionine relative to the TIC4064 protein.

Expression cassettes and vectors containing a recombinant nucleic acid molecule sequence can be constructed and introduced into plants, in particular corn, soybean or cotton plant cells in accordance with transformation methods and techniques known in the art. For example, Agrobacterium-mediated transformation is described in U.S. Patent Application Publications 2009/0138985A1 (soybean), 2008/0280361A1 (soybean), 2009/0142837A1 (corn), 2008/0282432 (cotton), 2008/0256667 (cotton), 2003/0110531 (wheat), 2001/0042257 A1 (sugar beet), in U.S. Pat. No. 5,750,871 (canola), 7,026,528 (wheat), and 6,365,807 (rice), and in Arencibia et al. (1998) Transgenic Res. 7:213-222 (sugarcane)) all of which are incorporated herein by reference in their entirety. Transformed cells can be regenerated into transformed plants that express TIC4064 and amino acid sequence variant proteins and demonstrate pesticidal activity through bioassays performed in the presence of Lepidopteran pest larvae using plant leaf disks obtained from the transformed plants. Plants can be derived from the plant cells by regeneration, seed, pollen, or meristem transformation techniques. Methods for transforming plants are known in the art.

As an alternative to traditional transformation methods, a DNA sequence, such as a transgene, expression cassette(s), etc., may be inserted or integrated into a specific site or locus within the genome of a plant or plant cell via site-directed integration. Recombinant DNA construct(s) and molecule(s) of this disclosure may thus include a donor template sequence comprising at least one transgene, expression cassette, or other DNA sequence for insertion into the genome of the plant or plant cell. Such donor template for site-directed integration may further include one or two homology arms flanking an insertion sequence (i.e., the sequence, transgene, cassette, etc., to be inserted into the plant genome). The recombinant DNA construct(s) of this disclosure may further comprise an expression cassette(s) encoding a site-specific nuclease and/or any associated protein(s) to carry out site-directed integration. These nuclease expressing cassette(s) may be present in the same molecule or vector as the donor template (in cis) or on a separate molecule or vector (in trans). Several methods for site-directed integration are known in the art involving different proteins (or complexes of proteins and/or guide RNA) that cut the genomic DNA to produce a double strand break (DSB) or nick at a desired genomic site or locus. Briefly as understood in the art, during the process of repairing the DSB or nick introduced by the nuclease enzyme, the donor template DNA may become integrated into the genome at the site of the DSB or nick. The presence of the homology arm(s) in the donor template may promote the adoption and targeting of the insertion sequence into the plant genome during the repair process through homologous recombination, although an insertion event may occur through non-homologous end joining (NHEJ). Examples of site-specific nucleases that may be used include zinc-finger nucleases, engineered or native meganucleases, TALE-endonucleases, and RNA-guided endonucleases (e.g., Cas9 or Cpf1). For methods using RNA-guided site-specific nucleases (e.g., Cas9 or Cpf1), the recombinant DNA construct(s) will also comprise a sequence encoding one or more guide RNAs to direct the nuclease to the desired site within the plant genome.

Recombinant nucleic acid molecule compositions that encode bacterial and plant expressed TIC4064, TIC4064_1 or TIC4064 amino acid sequence variant proteins can be expressed with recombinant DNA constructs in which a polynucleotide molecule with an ORF encoding the protein is operably linked to genetic expression elements such as a promoter and any other regulatory element necessary for expression in the system for which the construct is intended. Non-limiting examples include a plant-functional promoter operably linked to a TIC4064_1 protein or protein variant encoding sequence for expression of the protein in plants or a Bt-functional promoter operably linked to a TIC4064 protein or TIC4064 protein variant encoding sequence for expression of the protein in a Bt bacterium or other Bacillus species. Other elements can be operably linked to the TIC4064 protein toxin class protein encoding sequence including, but not limited to, enhancers, introns, untranslated leaders, encoded protein immobilization tags (HIS-tag), translocation peptides (i.e., plastid transit peptides, signal peptides), polypeptide sequences for post-translational modifying enzymes, ribosomal binding sites, and RNAi target sites. Exemplary recombinant polynucleotide molecules provided herewith include, but are not limited to, a heterologous promoter operably linked to a polynucleotide such as SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:29, SEQ ID NO:31, SEQ ID NO:33, SEQ ID NO:35, SEQ ID NO:37, SEQ ID NO:39, SEQ ID NO:41, SEQ ID NO:43, SEQ ID NO:45, SEQ ID NO:47, SEQ ID NO:49, and SEQ ID NO:51 that encodes the respective polypeptides or proteins having the amino acid sequence as set forth in SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:14, SEQ ID NO:16, SEQ ID NO:18, SEQ ID NO:20, SEQ ID NO:22, SEQ ID NO:24, SEQ ID NO:26, SEQ ID NO:28, SEQ ID NO:30, SEQ ID NO:32, SEQ ID NO:34, SEQ ID NO:36, SEQ ID NO:38, SEQ ID NO:40, SEQ ID NO:42, SEQ ID NO:44, SEQ ID NO:46, SEQ ID NO:48, SEQ ID NO:50, and SEQ ID NO:52. A heterologous promoter can also be operably linked to synthetic DNA coding sequences encoding a plastid targeted TIC4064_1 or TIC4064_1 protein variant. The codons of a recombinant nucleic acid molecule encoding for proteins disclosed herein can be substituted by synonymous codons (known in the art as a silent substitution).

A recombinant DNA construct comprising a sequence encoding one or more proteins from the TIC4064 protein toxin class can further comprise a region of DNA that encodes for one or more insect inhibitory agents which can be configured to concomitantly express or co-express with another protein from the TIC4064 protein toxin class, another insect control protein toxin, an insect inhibitory dsRNA molecule, or an ancillary protein. Ancillary proteins include, but are not limited to, co-factors, enzymes, binding-partners, or other agents that function to aid in the effectiveness of an insect inhibitory agent, for example, by aiding its expression, influencing its stability in plants, optimizing free energy for oligomerization, augmenting its toxicity, and increasing its spectrum of activity. An ancillary protein may facilitate the uptake of one or more insect inhibitory agents, for example, or potentiate the toxic effects of the toxic agent.

A recombinant DNA construct can be assembled so that all proteins or dsRNA molecules are expressed from one promoter or each protein or dsRNA molecule is under separate promoter control or some combination thereof. The proteins of this invention can be expressed from a multi-gene expression system in which one or more proteins of the TIC4064 protein toxin class are expressed from a common nucleotide segment which also contains other open reading frames and promoters, depending on the type of expression system selected. For example, a bacterial multi-gene expression system can utilize a single promoter to drive expression of multiply-linked/tandem open reading frames from within a single operon (i.e., polycistronic expression). In another example, a plant multi-gene expression system can utilize multiply-unlinked or linked expression cassettes, each cassette expressing a different protein or other agent such as one or more dsRNA molecules.

Recombinant polynucleotides or recombinant DNA constructs comprising a TIC4064 protein toxin class encoding sequence can be delivered to host cells by vectors, e.g., a plasmid, baculovirus, synthetic chromosome, virion, cosmid, phagemid, phage, or viral vector. Such vectors can be used to achieve stable or transient expression of a TIC4064 protein toxin class encoding sequence in a host cell, or subsequent expression of the encoded polypeptide. An exogenous recombinant polynucleotide or recombinant DNA construct that comprises a TIC4064 protein toxin class encoding sequence and that is introduced into a host cell is referred in this application as a “transgene”.

Transgenic bacteria, transgenic plant cells, transgenic plants, and transgenic plant parts that contain a recombinant polynucleotide that expresses any one or more of TIC4064. TIC4064_1, or the amino acid sequence variants thereof, or a related family toxin protein encoding sequence are provided herein. The term “bacterial cell” or “bacterium” can include, but is not limited to, an Agrobacterium, a Bacillus, an Escherichia, a Salmonella, a Pseudomonas, Brevibacillus, Klebsiella, Erwinia, or a Rhizobium cell. The term “plant cell” or “plant” can include but is not limited to a dicotyledonous or monocotyledonous plant. The term “plant cell” or “plant” can also include but is not limited to an alfalfa, banana, barley, bean, broccoli, cabbage, brassica (e.g. canola), carrot, cassava, castor, cauliflower, celery, chickpea, Chinese cabbage, citrus, coconut, coffee, corn (i.e. maize such as sweet corn or field corn), clover, cotton, a cucurbit, cucumber, Douglas fir, eggplant, eucalyptus, flax, garlic, grape, hops, leek, lettuce, Loblolly pine, millets, melons, nut, oat, olive, onion, ornamental, palm, pasture grass, pea, peanut, pepper, pigeonpea, pine, potato, poplar, pumpkin, Radiata pine, radish, rapeseed, rice, rootstocks, rye, safflower, shrub, sorghum, Southern pine, soybean, spinach, squash, strawberry, sugar beet, sugarcane, sunflower, sweet gum, sweet potato, switchgrass, tea, tobacco, tomato, triticale, turf grass, watermelon, and wheat plant cell or plant. In certain embodiments, transgenic plants and transgenic plant parts regenerated from a transgenic plant cell are provided. In certain embodiments, the transgenic plants can be obtained from a transgenic seed, by cutting, snapping, grinding or otherwise disassociating the part from the plant. In certain embodiments, the plant part can be a seed, a boll, a leaf, a flower, a stem, a root, or any portion thereof, or a non-regenerable portion of a transgenic plant part. As used in this context, a “non-regenerable” portion of a transgenic plant part is a portion that cannot be induced to form a whole plant or that cannot be induced to form a whole plant that is capable of sexual and/or asexual reproduction. In certain embodiments, a non-regenerable portion of a plant part is a portion of a transgenic seed, boll, leaf, flower, stem, or root.

Methods of making transgenic plants that comprise insecticidally effective Lepidoptera-inhibitory amounts of a protein from the TIC4064 protein toxin class are provided. Such plants can be made by introducing a recombinant polynucleotide that encodes any of the proteins provided in this application into a plant cell, and selecting a plant derived from said plant cell that expresses an insecticidally effective Lepidoptera-inhibitory amount of the proteins. Plants can be derived from the plant cells by regeneration, seed, pollen, or meristem transformation techniques. Methods for transforming plants are known in the art.

Processed plant products, wherein the processed product comprises a detectable amount of a TIC4064 toxin protein class protein, an insect inhibitory segment or fragment thereof, or any distinguishing portion thereof, are also disclosed herein. In certain embodiments, the processed product is selected from the group consisting of plant parts, plant biomass, oil, meal, sugar, animal feed, flour, flakes, bran, lint, hulls, processed seed, and seed. In certain embodiments, the processed product is non-regenerable. The plant product can comprise commodity or other products of commerce derived from a transgenic plant or transgenic plant part, where the commodity or other products can be tracked through commerce by detecting nucleotide segments or expressed RNA or proteins that encode or comprise distinguishing portions of a TIC4064 protein.

Plants expressing proteins from the TIC4064 protein toxin class can be crossed by breeding with transgenic events expressing other toxin proteins and/or expressing other transgenic traits such as herbicide tolerance genes, genes conferring yield or stress tolerance traits, and the like, or such traits can be combined in a single stacked vector so that the traits are all linked.

As further described in the Examples, TIC4064 protein toxin class encoding sequences and sequences having a substantial percentage identity to the TIC4064 protein toxin class can be identified using methods known to those of ordinary skill in the art such as polymerase chain reaction (PCR), thermal amplification, and hybridization. For example, the proteins from the TIC4064 protein toxin class can be used to produce antibodies that bind specifically to related proteins and can be used to screen for and to find other protein members that are closely related.

Furthermore, nucleotide sequences encoding proteins in the TIC4064 toxin protein class can be used as probes and primers for screening to identify other members of the class using thermal-cycle or isothermal amplification and hybridization methods. For example, oligonucleotides derived from sequences as set forth in SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:29, or SEQ ID NO:31 can be used to determine the presence or absence of a protein from the TIC4064 protein toxin class in a deoxyribonucleic acid sample derived from a commodity product. Given the sensitivity of certain nucleic acid detection methods that employ oligonucleotides, it is anticipated that oligonucleotides derived from sequences as set forth in SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:29, and SEQ ID NO:31 can be used to detect a TIC4064_1, TIC4064_2, TIC4064_3, TIC4064_4, TIC4064_5, TIC4064_6, TIC4064_12_1, TIC4064_12_2, TIC4064_13, TIC4064_14, TIC4064_15, TIC4064_16, TIC4064_17, TIC4064_18, or TIC4064_19 transgene in commodity products derived from pooled sources where only a fraction of the commodity product is derived from a transgenic plant containing any of the transgenes. It is further recognized that such oligonucleotides can be used to introduce nucleotide sequence variation in each of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:29, SEQ ID NO:31, SEQ ID NO:33, SEQ ID NO:35, SEQ ID NO:37, SEQ ID NO:39, SEQ ID NO:41, SEQ ID NO:43, SEQ ID NO:45, SEQ ID NO:47, SEQ ID NO:49, and SEQ ID NO:51. Such “mutagenesis” oligonucleotides are useful for identification of TIC4064 protein toxin class amino acid sequence variants exhibiting a range of insect inhibitory activity or varied expression in transgenic plant host cells.

Nucleotide sequence homologs, e.g., insecticidal proteins encoded by nucleotide sequences that hybridize to each or any of the sequences disclosed in this application under stringent hybridization conditions, are also an embodiment of the present invention. The invention also provides a method for detecting a first nucleotide sequence that hybridizes to a second nucleotide sequence, wherein the first nucleotide sequence (or its reverse complement sequence) encodes a pesticidal protein or pesticidal fragment thereof and hybridizes to the second nucleotide sequence. In such case, the second nucleotide sequence can be any of the nucleotide sequences presented as SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:29, SEQ ID NO:31, SEQ ID NO:33, SEQ ID NO:35, SEQ ID NO:37, SEQ ID NO:39, SEQ ID NO:41, SEQ ID NO:43, SEQ ID NO:45, SEQ ID NO:47, SEQ ID NO:49, or SEQ ID NO:51 under stringent hybridization conditions. Nucleotide coding sequences hybridize to one another under appropriate hybridization conditions, such as stringent hybridization conditions, and the proteins encoded by these nucleotide sequences cross react with antiserum raised against any one of the other proteins. Stringent hybridization conditions, as defined herein, comprise at least hybridization at 42° C. followed by two washes for five minutes each at room temperature with 2×SSC, 0.1% SDS, followed by two washes for thirty minutes each at 65° C. in 0.5×SSC, 0.1% SDS. Washes at even higher temperatures constitute even more stringent conditions, e.g., hybridization conditions of 68° C., followed by washing at 68° C., in 2×SSC containing 0.1% SDS.

One skilled in the art will recognize that, due to the redundancy of the genetic code, many other sequences are capable of encoding such related proteins, and those sequences, to the extent that they function to express pesticidal proteins either in Bacillus strains or in plant cells, are embodiments of the present invention, recognizing of course that many such redundant coding sequences will not hybridize under these conditions to the native Bacillus sequences encoding TIC4064 and TIC4064 amino acid sequence variants. This application contemplates the use of these and other identification methods known to those of ordinary skill in the art, to identify TIC4064 and TIC4064 amino acid sequence variant protein-encoding sequences and sequences having a substantial percentage identity to TIC4064 and TIC4064 amino acid sequence variants protein-encoding sequences.

This disclosure also contemplates the use of molecular methods known in the art to engineer and clone commercially useful proteins comprising chimeras of proteins from pesticidal proteins; e.g., the chimeras may be assembled from segments of the TIC4064 or TIC4064 amino acid sequence variant proteins to derive additional useful embodiments including assembly of segments of TIC4064 or TIC4064 amino acid sequence variant proteins with segments of diverse proteins different from TIC4064 or TIC4064 amino acid sequence variant proteins and related proteins. The TIC4064 or TIC4064 amino acid sequence variant proteins may be subjected to alignment to each other and to other Bacillus, Paenibacillus or other pesticidal proteins (whether or not these are closely or distantly related phylogenetically), and segments of each such protein may be identified that are useful for substitution between the aligned proteins, resulting in the construction of chimeric proteins. Such chimeric proteins can be subjected to pest bioassay analysis and characterized for the presence or absence of increased bioactivity or expanded target pest spectrum compared to the parent proteins from which each such segment in the chimera was derived. The pesticidal activity of the polypeptides may be further engineered for activity to a particular pest or to a broader spectrum of pests by swapping domains or segments with other proteins or by using directed evolution methods known in the art.

Methods of controlling insects, in particular Lepidoptera infestations of crop plants, with the TIC4064 or TIC4064 amino acid sequence variant proteins are disclosed in this application. Such methods can comprise growing a plant comprising an insect- or Lepidoptera-inhibitory amount of a TIC4064 or TIC4064 amino acid sequence variant toxin protein. In certain embodiments, such methods can further comprise any one or more of: (i) applying any composition comprising or encoding a TIC4064 or TIC4064 amino acid sequence variant toxin protein to a plant or a seed that gives rise to a plant; and (ii) transforming a plant or a plant cell that gives rise to a plant with a polynucleotide encoding a TIC4064 or TIC4064 amino acid sequence variant toxin protein. In general, it is contemplated that a TIC4064 or TIC4064 amino acid sequence variant toxin protein can be provided in a composition, provided in a microorganism, or provided in a transgenic plant to confer insect inhibitory activity against Lepidopteran insects.

In certain embodiments, a recombinant nucleic acid molecule of TIC4064 or TIC4064 amino acid sequence variant toxin protein is the insecticidally active ingredient of an insect inhibitory composition prepared by culturing recombinant Bacillus or any other recombinant bacterial cell transformed to express a TIC4064 or TIC4064 amino acid sequence variant toxin protein under conditions suitable to express the TIC4064 or TIC4064 amino acid sequence variant toxin protein. Such a composition can be prepared by desiccation, lyophilization, homogenization, extraction, filtration, centrifugation, sedimentation, or concentration of a culture of such recombinant cells expressing/producing said recombinant polypeptide. Such a process can result in a Bacillus or other entomopathogenic bacterial cell extract, cell suspension, cell homogenate, cell lysate, cell supernatant, cell filtrate, or cell pellet. By obtaining the recombinant polypeptides so produced, a composition that includes the recombinant polypeptides can include bacterial cells, bacterial spores, and parasporal inclusion bodies and can be formulated for various uses, including as agricultural insect inhibitory spray products or as insect inhibitory formulations in diet bioassays.

In one embodiment, to reduce the likelihood of resistance development, an insect inhibitory composition comprising TIC4064 or TIC4064 amino acid sequence variant protein can further comprise at least one additional polypeptide that exhibits insect inhibitory activity against the same Lepidopteran insect species, but which is different from the TIC4064 or TIC4064 amino acid sequence variant toxin protein. Possible additional polypeptides for such a composition include an insect inhibitory protein and an insect inhibitory dsRNA molecule. One example for the use of such ribonucleotide sequences to control insect pests is described in Baum, et al. (U.S. Patent Publication 2006/0021087 A1). Such additional polypeptide for the control of Lepidopteran pests may be selected from the group consisting of an insect inhibitory protein, such as, but not limited to, Cry1A (U.S. Pat.

In other embodiments, such composition/formulation can further comprise at least one additional polypeptide that exhibits insect inhibitory activity to an insect that is not inhibited by an otherwise insect inhibitory protein of the present invention to expand the spectrum of insect inhibition obtained. For example, for the control of Hemipteran pests, combinations of insect inhibitory proteins of the present invention can be used with Hemipteran-active proteins such as TIC1415 (US Patent Publication 2013-0097735 A1), TIC807 (U.S. Pat.

Further a polypeptide for the control of Coleopteran pests may be selected from the group consisting of an insect inhibitory protein, such as, but not limited to, Cry3Bb (U.S. Pat. No. 6,501,009), Cry1C variants, Cry3A variants, Cry3, Cry3B, Cry34/35, 5307, AXMI134 (U.S. Patent Publication 2013-0167264 A1) AXMI-184 (U.S. Patent Publication 2010-0004176 A1), AXMI-205 (U.S. Patent Publication 2014-0298538 A1), AXMI-207 (U.S. Patent Publication 2013-0303440 A1), AXMI-218, AXMI -220 (U.S. Patent Publication 20140245491A1), AXMI-221z, AXMI-223z (U.S. Patent Publication 2014-0196175 A1), AXMI-279 (U.S. Patent Publication 2014-0223599 A1), AXMI-R1 and variants thereof (U.S. Patent Publication 2010-0197592 A1, TIC407, TIC417, TIC431, TIC807, TIC853, TIC901, TIC1201, TIC3131, DIG-10 (U.S. Patent Publication 2010-0319092 A1), eHIPs (U.S. Patent Application Publication No. 2010/0017914), IP3 and variants thereof (U.S. Patent Publication 2012-0210462 A1), Pseudomonas toxin DP072Aa (US Patent Application Publication No. 2014/055128), and ω-Hexatoxin-Hv1a (U.S. Patent Application Publication US2014-0366227 A1).

Additional polypeptides for the control of Coleopteran, Lepidopteran, and Hemipteran insect pests, which can be combined with the insect inhibitory proteins of the TIC4064 family, can be found on the Bacillus thuringiensis toxin nomenclature website maintained by Neil Crickmore (on the world wide web at btnomenclature.info). Broadly, it is contemplated that any insect inhibitory protein known to those of skill in the art can be used in combination with the TIC4064 family in both in planta (combined through breeding or molecular stacking) or in a composition or formulation as a biopesticide or combination of biopesticides.

The possibility for insects to develop resistance to certain insecticides has been documented in the art. One insect resistance management strategy is to employ transgenic crops that express two distinct insect inhibitory agents that operate through different modes of action. Therefore, any insects with resistance to either one of the insect inhibitory agents can be controlled by the other insect inhibitory agent. Another insect resistance management strategy employs the use of plants that are not protected to the targeted Lepidopteran pest species to provide a refuge for such unprotected plants. One particular example is described in U.S. Pat. No. 6,551,962, which is incorporated by reference in its entirety.

Other embodiments such as topically applied pesticidal chemistries that are designed for controlling pests that are also controlled by the proteins disclosed herein to be used with proteins in seed treatments, spray on, drip on, or wipe on formulations can be applied directly to the soil (a soil drench), applied to growing plants expressing the proteins disclosed herein, or formulated to be applied to seed containing one or more transgenes encoding one or more of the proteins disclosed. Such formulations for use in seed treatments can be applied with various stickers and tackifiers known in the art. Such formulations can contain pesticides that are synergistic in mode of action with the proteins disclosed, so that the formulation pesticides act through a different mode of action to control the same or similar pests that can be controlled by the proteins disclosed, or that such pesticides act to control pests within a broader host range or plant pest species that are not effectively controlled by the TIC4064 and TIC4064 amino acid sequence variant pesticidal proteins.

The aforementioned composition/formulation can further comprise an agriculturally-acceptable carrier, such as a bait, a powder, dust, pellet, granule, spray, emulsion, a colloidal suspension, an aqueous solution, a Bacillus spore/crystal preparation, a seed treatment, a recombinant plant cell/plant tissue/seed/plant transformed to express one or more of the proteins, or bacterium transformed to express one or more of the proteins. Depending on the level of insect inhibitory or insecticidal inhibition inherent in the recombinant polypeptide and the level of formulation to be applied to a plant or diet assay, the composition/formulation can include various by weight amounts of the recombinant polypeptide, e.g. from 0.0001% to 0.001% to 0.01% to 1% to 99% by weight of the recombinant polypeptide.

In view of the foregoing, those of skill in the art should appreciate that changes can be made in the specific aspects which are disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention.

EXAMPLES Example 1 Discovery, Cloning, and Expression of TIC4064 and Engineered Amino Acid Sequence Variants of TIC4064

A sequence encoding a novel Bacillus thuringiensis (Bt) pesticidal protein was identified, cloned, sequence confirmed, and tested in insect bioassay. The pesticidal protein, TIC4064, was isolated from Bt species EG9820 and represents a novel Cry9Aa-related protein. Bt strain EG9820 was initially identified as a spore forming, crystal and plasmid containing strain of Bt or Bt-like bacteria. DNA was isolated from EG9820 and sequenced. The assembled sequence was then analyzed and an open reading frame encoding the TIC4064 protein was identified by pfam analysis to hits of endotoxin domains and identity to known Cry9Aa toxins. The full length TIC4064 protein amino acid sequence exhibits 98.1% identity to GenBank accession WP_087976765 annotated as a hypothetical protein which has not been assayed against insect pest species. GenBank accession CAA41425 is 97.58% identical to the full length TIC4064 protein. CAA41425 demonstrated 70% mortality in diet bioassay to first instar larvae of Epiphyas postvittana (light brown apple moth), however the authors were unable to isolate sufficient amounts of protein to assay other insect pests (Gleave et al., Journal of General Microbiology 138:55-62, 1992). Polymerase chain reaction (PCR) primers were designed to amplify a full length copy of the coding region for TIC4064 from total genomic DNA isolated from the Bt species EG9820. The PCR amplicon also included the translational initiation and termination codons of the coding sequence.

The TIC4064 coding sequence was cloned using methods known in the art into a Bt expression vector in operable linkage with a Bt expressible promoter. Spore and soluble protein preparations were used in bioassay. In addition, variants of TIC4064 were produced which comprised selected amino acid substitutions. The coding sequences encoding these TIC4064 amino acid sequence variants were synthesized and cloned into a bacterial expression vector used for expression of the protein in E. coli. Protein preparations of the TIC4064 amino acid sequence variants were used in bioassay. Table 7 shows the bacterial TIC4064 amino acid sequence variants and the amino acid substitutions that were introduced relative to the bacterial TIC4064 protein sequence.

Example 2 TIC4064 and the TIC4064 Amino Acid Sequence Variants Demonstrates Lepidopteran Activity in Insect Bioassay

The pesticidal proteins TIC4064, and the TIC4064 amino acid sequence variants TIC4064_20, TIC4064_21, TIC4064_22, TIC4064_23, TIC4064_24, TIC4064_25, TIC4064_26, TIC4064_27, TIC4064_10, and TIC4064_11 were expressed in either Bt or E. coli and assayed for toxicity to various species of Lepidoptera. TIC4064 was also assayed for toxicity to various species of Coleoptera, Hemiptera, and Diptera.

TIC4064 was assayed for toxicity to the Lepidopteran insect species Black cutworm (BCW, Agrotis ipsilon), Corn earworm (CEW, Helicoverpa zea, also known as Soybean podworm), European corn borer (ECB, Ostrinia nubilalis), Fall armyworm (FAW, Spodoptera frugiperda), Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Southwestern corn borer (SWC, Diatraea grandiosella), Tobacco budworm (TBW, Heliothis virescens), Sunflower looper (SFL, Rachiplusia nu), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis); the Coleopteran species Colorado potato beetle (CPB, Leptinotarsa decemlineata) and Western Corn Rootworm (WCR, Diabrotica virgifera); the Hemipteran species Neotropical Brown Stink Bug (NBSB, Euschistus heros); and the Dipteran species Yellow Fever Mosquito (YFM, Aedes aegypti). Bioassay using microbial host cell-derived proteins of TIC4064 demonstrated activity against the Lepidopteran species BCW, CEW, ECB, SAW, SBL, SWC, SFL, TBW, and VBC. Activity was also observed against the Dipteran species YFM.

The bacterial TIC4064 amino acid sequence variants TIC4064_20, TIC4064_21, TIC4064_22, TIC4064_23, TIC4064_24, TIC4064_25, TIC4064_26, and TIC4064_27 were assayed only against CEW to determine if the amino acid modifications affected CEW activity. All of the TIC4064 amino acid sequence variants retained activity against CEW. TIC4064_10 and TIC4064_11 were assayed against CEW, SAW, SBL and VBC and demonstrated activity against each pest species. In addition, TIC4064_10 and TIC4064_11 were assayed against Black armyworm (BAW, Spodoptera cosmioides) in a dilution assay. Both TIC4064_10 and TIC4064_11 demonstrated activity against BAW.

Example 3 Design of Synthetic Coding Sequences for TIC4064 and TIC4064 Amino Acid Sequence Variants for Use in Expression in Plants

Synthetic (artificial) coding sequences were designed for expression in plant cells encoding TIC4064 and amino acid sequence variants of TIC4064. In addition, coding sequences were also designed which encoded TIC4064 and TIC4064 amino acid sequence variants comprising a deletion of the protoxin domain.

The synthetic sequences were synthesized, according to methods generally described in U.S. Pat. No. 5,500,365, to avoid certain inimical problem sequences such as ATTTA and A/T rich plant polyadenylation sequences while preserving the amino acid sequence of the native Bacillus protein. TIC4064_1 (SEQ ID NO:3) is the plant synthetic coding sequence of TIC4064, and encodes a TIC4064_1 protein (SEQ ID NO:4) which includes an additional alanine residue immediately following the initiating methionine relative to the TIC4064 protein. Synthetic coding sequences were also synthesized encoding amino acid sequence variants of TIC4064_1 wherein specific amino acids were substituted. In addition, synthetic coding sequences encoding truncations of the protoxin domain of the TIC4064_1 amino acid sequence variants were synthesized. All of the TIC4064_1 amino acid sequence variants comprised an additional alanine residue immediately following the initiating methionine. Table 8 shows each of the TIC4064_1 variants and the corresponding amino acid changes relative to both TIC4064_1 and bacterial TIC4064.

Binary plant transformation vectors comprising targeted and untargeted TIC4064_1 and the TIC4064_1 amino acid sequence variant synthetic coding sequences were constructed using methods known in the art. The resulting transformation vectors comprised a first transgene cassette for expression of the TIC4064_1 and the TIC4064_1 amino acid sequence variant pesticidal proteins which comprised a constitutive promoter, operably linked 5′ to a leader, operably linked 5′ to a synthetic coding sequence encoding a plastid targeted or untargeted TIC4064_1 or TIC4064_1 amino acid sequence variant protein, which was in turn operably linked 5′ to a 3′ UTR and; a second transgene cassette for the selection of transformed plant cells using spectinomycin selection.

Example 4 TIC4064_1 and the TIC4064_1 Amino Acid Sequence Variants Demonstrate Lepidopteran Activity in Stably Transformed Soybean Plants

Binary plant transformation vectors comprising transgene cassettes designed to express both plastid targeted and untargeted TIC4064_1 and TIC4064_1 amino acid sequence variant pesticidal proteins were cloned using methods known in the art. The resulting vectors were used to stably transform soybean plants. Tissues were harvested from the transformants and used in insect bioassay against various Lepidopteran insect species.

Soybean plants were transformed with the binary transformation vectors described in Example 3 using an Agrobacterium-mediated transformation method. The transformed cells were induced to form plants by methods known in the art. Bioassays using plant leaf disks were performed analogous to those described in U.S. Pat. No. 8,344,207. A single freshly hatched neonate larvae less than one day old was placed on each leaf disc sample and allowed to feed for approximately four days. A non-transformed soybean plant was used to obtain tissue to be used as a negative control. Multiple transformation R₀ single-copy insertion events from each binary vector were assessed against Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Soybean podworm (SPW, Helicoverpa zea,), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis). An efficacy rating score which ranged from 0 to 3 was assigned to each event based upon the percent leaf damage in the bioassay for each event and the percent events that shared the lowest percent range of damage (Penetrance) as shown in Table 9.

TABLE 9 Efficacy rating scores. Efficacy score Percent Leaf Damage Penetrance 0 >50% ≥80% 1 <50% ≥20% 2 <30% ≥20% 3 ≤10% ≥50%

Table 10 shows the efficacy scores for R₀ stably transformed soybean plants expressing the TIC4064_1 or TIC4064_1 amino acid sequence variants described in Example 3, Table 8. The numbers in parenthesis represent the number of events that shared the lowest percent range of damage/total number of events assayed. For TIC4064_3, TIC4064_4, TIC4064_5, TIC4064_13, TIC4064_14, TIC4064_5, TIC4064_17, TIC4064_18, and TIC4064_19 multiple constructs were used to transform plants, each comprising different expression elements. The constructs expressing the toxin proteins TIC4064_3, TIC4064_4, TIC4064_13, TIC4064_14, TIC4064_15, TIC4064_17, TIC4064_18, and TIC4064_19 each included an amino terminal chloroplast transit peptide linked to the pesticidal protein for the purpose of targeting the respective protein to the chloroplast.

As can be seen in Table 10, stably transformed R₀ soybean plants expressing TIC4064_1 and the TIC4064_1 amino acid sequence variants demonstrated efficacy against SBL and VBC. The majority of the R₀ stably transformed soybean plants demonstrated efficacy or suppression of SAW.

Selected R₀ events expressing TIC4064_1, TIC4064_2, TIC4064_3, TIC4064_4, and TIC4064_6 were allowed to self-pollinate and produce R₁ seed. The R₁ seed was used to grow R₁ plants. R₁ plants homozygous for the pesticidal protein expression cassette were selected for leaf disc bioassay against SAW, SBL, SPW and VBC. As can be seen in Table 11 below, R₁ plants expressing TIC4064_1, TIC4064_2, TIC4064_3, TIC4064_4, and TIC4064_6 demonstrated efficacy against SBL and VBC, and suppression of SAW.

TIC4064_1 and TIC4064_2 are efficacious against SAW. The majority of the TIC4064_1 amino acid sequence variants demonstrated suppression of SAW.

Example 5 TIC4064_3 and TIC4064_4 are Efficacious Against Soybean Looper, Sunflower Looper, and Velvet Bean Caterpillar and Provide Suppression of South American Podworm, Southern Armyworm, and Sunflower Looper in Screenhouse Trials

Soybean plants expression TIC4064_3 and the truncated TIC4064_3, TIC4064_4 were assayed for protection against selected insect pest species in screenhouse trials in the United States and in Argentina.

In the United States, Soybean plants expressing TIC4064_3 were assayed in several locations in screenhouse trials against Southern armyworm (SAW, Spodoptera eridania), Soybean looper (SBL, Chrysodeixis includens), Soybean podworm (SPW, Helicoverpa zea,), and Velvet bean caterpillar (VBC, Anticarsia gemmatalis) in several locations. Screenhouse trials were conducted in Jerseyville, Ill. against SAW and SBL, in Union City, Tenn. against SBL, and against VBC and SPW in Waterman, Ill. The events were evaluated using a randomized complete block design. Each plot was planted in a single six (6) foot row with approximately eight (8) seeds per foot. Each event was represented in the screenhouse by three (3) separate plots, randomly located within the screenhouse. A non-transformed event served as a negative control, and this even was also assigned randomly to locations within the screenhouse.

Infestation of SPW and VBC was accomplished using adult moths. The insects were reared to pupae in an insectary in adult emergence cages, and maintained in climate-controlled incubators. The pupae were shipped to specific locations for release in the screenhouses. Approximately one thousand two hundred (1,200) to two thousand (2,000) adults were used for each release in the screenhouses. For SPW, adults were released in the screenhouse each week from the R1 to R2 stage of soybean development. With respect to VBC, adults were released in the screenhouse bi-weekly between the developmental stages of V4 to R3. Adult moths required continuous access to a ten percent (10%) sucrose solution for normal longevity and fecundity. Plastic food containers were filled with absorbent cotton and then the sugar solution was poured into the container to completely saturate the cotton. The sugar solution was replenished daily until adult activity subsided which was usually around two weeks after the final release of adults. Direct egg infestation was used for SAW since this insect does not oviposit preferentially or uniformly on soybean. Approximately two hundred fifty thousand (250,000) to three hundred twenty thousand (320,000) eggs were used for each infestation, and applied bi-weekly from R1 to R3 stage of development. Pieces of paper containing equal numbers of SAW eggs were attached to plants by folding the paper over a sturdy leaf petiole in the upper canopy and stapling the paper together securely. One paper was placed on a plant within one (1) foot of the front end of the plot, a second paper was placed on a plant in the middle of the plot, and a third paper was placed on a plant within one (1) foot of the back end of the plot.

The percent defoliation was assessed at different stages of plant development. For SAW, percent defoliation was assessed at the R2.8, R4.1, R4.8, and R6.0 developmental stages at Jerseyville, Ill. For SBL, percent defoliation was determined at the R2.0, R3.1, R4.2, and R5.5 developmental stages Union City, Tenn., and at the R5.4 and R5.8 developmental stages at Jerseyville, Ill. For VBC, percent defoliation was assessed at the R3.9, R5.0, and R5.4 developmental stages at Waterman, Ill. For SPW, percent defoliation was assessed at the R4.1, R4.7, R5.4, and R5.8 developmental stages at Waterman, Ill. A maximum percent defoliation was derived from the highest percent defoliation observed amongst the different developmental stages for each insect. Table 12 shows the average maximum percent defoliation for plants expressing TIC4064_3 for SAW, SBL, and VBC. The average maximum percent defoliation for SPW was similar to the negative control and is not presented in Table 12.

TABLE 12 Average maximum percent defoliation for soybean plants expressing TIC4064_3 in United States screenhouse trials. SAW SBL VBC Location Neg TIC4064_3 Neg TIC4064_3 Neg TIC4064_3 Jerseyville, IL 56.5 9.9 25.0 0.0 Union City, TN 71.5 0.5 Waterman, IL 50.3 0.1

As can be seen in Table 12, plants expressing TIC4064_3 were efficacious in controlling SBL and VBC. In addition, plants expressing TIC4064_3 demonstrated suppression of SAW.

Screenhouse trials were also conducted in Argentina at two locations, Fran Luis, B A and Pergamino, BA for soybean plants expressing TIC4064_3 and TIC4064_4. Screenhouse trials were conducted in a similar manner as those in the United States. Each plot in the screenhouse comprised a row of forty-two (42) seeds in a two (2) meter row. Each event was represented in the screenhouse by three (3) randomly located separate plots. Screenhouse trials were conducted against the specified Lepidopteran insect pests.

The percent defoliation was assessed at different stages of plant development. For SBL, percent defoliation was assessed at the R5.0, R5.5, and R6.0 developmental stages at Fran Luis, BA and at the R4.0, R5.1, and R5.6 developmental stages at Pergamino, BA. For VBC, percent defoliation was assessed at the R5.5, R6.0, and R6.5 developmental stages at Fran Luis, BA and at the R5.0, R5.6, and R6.0 developmental stages at Pergamino, BA. For SFL, percent defoliation was assessed at the R5.0, R5.3, R5.5, and R6.0 developmental stages at Fran Luis, BA and at the R3.0, R4.0, R5.2, and R6.2 developmental stages at Pergamino, BA. For SAPW, percent defoliation was assessed at the R4.4, R5.1, R5.5, and R6.0 developmental stages at Fran Luis, BA and at the R3.0, R4.0, R5.1, R6.2 developmental stages at Pergamino, BA. A maximum percent defoliation was determined as above for each of the insect pests in each location. Table 13 shows the average maximum percent defoliation for plants expressing TIC4064_3 and TIC4064_4.

As can be seen in Table 13, soybean plants expressing TIC4064_3 and TIC4064_4 were efficacious against SBL, VBC, and SFL, and demonstrated suppression of SAPW.

TIC4064_3 TIC4064_4 are efficacious against SBL, VBC, and SFL and provide suppression of SAW and SAPW.
